'ihe builder motion :as now used in spinning; machines includes :i cam, the employment ot which is objectionable ter various ressens. lt requires heavy weights to more the builder arm or lever in opposition to the can. The motion 'from the cuni is not :ilieys smooth end easy but may be jerliy sind thus result in. improperly formed cops. )ne object oit my invention to provide a builder motion which will he tree 'from the just-noted objections. Another object ot my invention is to provide a builder motion Whose lever or arm Will move With great poner. @ther obieets and advantages ot' my invention w`ll be understood end appreciated by those skilled in the art when the enibodiment oi" such invention illustrated in the drawings is exphiined, some ot which pointed out hereinafter. ly invention consists in what is described by or is einbrficed within the meaning; or scope et" the appended claims.

The embodiment or" my iiircntion appearingl in the drawings is a ring-spinning niachine in which the ring' rails are stationary and the spindles ere trarersed1 and such ma- Ichine a type invented by nie in which the builder motion is located et midlerfrth ot the machine, het it is to be understood that mv inrention not .limited to machines in which the ring-rails are stationary and the spindles traverse but extends to machines in which the ring-rails are the traversing members, nor my invention limited to application to a machine in which the builder motion is at niiifllength, 'For it mey he embodied when 'the builder motion is etr one end and it'nmy be embodied in machines in which the ringrails are traversed and the builder motion is located at midleiigth of the machine.

in its general construction, the machine shown in the dreuingrs is similar to that ot' the machine of my United States Patent No. Llltlll, issued December 3T/2l, it having at inidlengrth ot the machine two heads, lll, spliced apart and between Which are mount-ed the driving mechanism Yfor the tin rollers ot the tivo sections ot the machine and the builder motiomthe driving` mechanism comprising. a belt, ll, which passes over pulleys, l2, which are mounted upon end partake ot vertical movement ot the csi-riegos, l-"l, upon which the spindles. hl, are mounted tor their traversingmovement through their rings, l5, mounted on stetionsry ring-rails, 1G, the threads ot vyar-n beine* delivered by trent feed or drew rollers to travelers l?, on the rings.

The builder lever or erm., 18. is pivoted or hunegat its upper end in a bracket, 19, which is bolted to the underside ot' e horizontal plete. 20, supported by the tivo heads, lo, and at its lower end it has a gear segment, With whichv meshes a driving; pinion1 2&2, which, es hereinafter explaine l` may be revolved in either direction and therelrv the swinging o r vibretory movement ot thelniilder erm, 18` isproduced.

'llhepinioin- 22, is en av short shzrtt, 2?), to which is tired e Worm Wheel, 24,- that is driven by :i Worm, 25, on a horizontal shzitt, QG, (ln the latter :ire pinned two oppositely tacinp; clutch collars. 27 and 28 respectively, sind loose onv the sha'lti'QG, between said collnrs is a slidzible sleeve, 29, that hes lined to itrtvco simi' `leere, 30 and 3l, of' different diem'eter, each having e clutch face so that alternately seid gears may be engaged with the. clutch collars, and thus theV Worm shartt. be driven by one `rear or thel other and at dil'ierent speeds. li'leshing with the larger gearn 30,' is a geur, 3Q, iixed to a shaft, 533, :ind also'on the she-tt7 33, isv ay smaller gear, Pfl.v which hy an idler `'eer, 35, is geared to the smaller gear, 31V, and thus, as the shett,

33, always rotates in the same direction, theworm shat't may be revolved'alternately in opposite directions and thereby the builder arm or lever be positively but easily swung to and fro and with a smooth or steady, and power't'ul motion. The shaft, 33, is mounted in bearings in a` traine, 35, and at one end has a bevel pinion, 37, which meshes with and receives motion from a bevel pinion, 38,011 a sha'tt, that has a sprocket wheel, il), which by gearing that includes a sprocket chain, stl, is driven from one or the other` pulleys, 12, asin the machine of my patentabove mentioned.

The clutch sleeve, 29, is engaged by a lug, t2, on a yolre, 43, whose arms, est, are pinned to a rod, 45, slidably mounted in the frame, 36. Upon the rod, 45, are two coiled springs, elf', which respectively bear at their outer ends against the yoke arms, est, and between the springs, lG, is a linger, 4T, that is attached to a rod, l-S, slidably mounted in the trame, 36, so that it may move to and tro. lVhen the rod, 4B, moves in one direction it acts to compress one spring` against one yoke arm and when moved in the opposite direction it acts to compress the other spring against the other yoke arm, the arm against which the spring is pushed being; held by a latch, 49, against movement until the latch is released, whereupon the spring` being tree to act it will quickly move the yoke longitudinally and thereby shit't the clutch sleeve, 29, to change the gear connection with the worm shaft. The latch, 49, has a. shoulder, 50, which drops back ot the voke arm, l-t, with which it enact-s, and its tree end has a bevelled nose, 5l, against which the linger, ft?, acts and a'tter a certain amount of movement ot the linge the latch camined out ot engagement with the volie arm. The movement ot the sprini`compressing and latcli-releasinp,- linger, All", is automatically prmluced by means oit motion obtained .trom the builder motion arm which means coinprises a pair ot spaced lues connected with such arm to partake ol its motion and an extension, 52, ot the finger, 4t?, which is situated between said lugs and is engaged h v one or the other according' to the dire/'- tion of movement ot the builder motion arm or lever. Said lugs may he carried by a rod pivotally connected at one end to the builder motion arm or lever, 18, but tor reasons that will presently appear, I prefer the construction illustrated in the drawings. ln the drawings, said lugs, 53, are each carried by a nut, 5%, upon a shaft, 55, that has right and lett hand threads to engage the respective nuts so that by its revolutitm in one direction the nuts will be moved towards one another and by its rotation in the oppositel direction, they will be moved awayl lrom each other. The shaft, 55, is mounted in bearings in atubular or hollow rod, 5G,

which at one end has a lateral extension, 5T, which has a sleeve, 58, through which passes a shaft, 59, supported by the builder motion arm or lever, 1S. Upon the shat't, 55, is a bevel pinion, GO, which meshes with a bevel pinion, 6l, loose on the shafjt, 5S), and attached to the hub ot said bevel pinion, (Sl, is a ratchet wheel, G2, with which coacts a pawl, 63, on an arm, 64, pivoted to the huh of the pinion, Gl, so that by the oscillation or the arin, 54, the atchet wheel may be turned intermittently and thereby the shait, 55, revolved and the movement oi' the nuls, 5d, and the lugs, 53, towards one another and towards the linger extension, 52, may be produced, this action being` automatic-ally produced when it is desired to wind the cops tor warp thread. At other times for form ing a, different cop, the lugs, 53, are set at the desired adjustment so that at the proper time they will alternately engage the finger extension, 52, to canse the shitting` ot the clutch sleeve to reverse the direction oi movement of the builder arm or lever, the tubular rod, 56, in such ease being simply moved to and tro with the builder. arm through its pivotal connection with the latter. The lugs, 53, project through a slot, 560, in the tubular rod, 56, and they and the finger extension, 52, are guided hy a rod, 561. which passes through holes in them and which at opposite ends is supported by lungs, 562, which project from the tubular rod, 56, then the automatic movement ot' the nuts, 5-l-, and the lugs, 'lor warp winding` is to he etlected a rod, (35, which at one end is pivoted to a bracket, Gti, attached stationaril)7 to one ot the heads, l0, is pivotaillv connected to aneye` (ST, as shown in dotted lines in Fig. ll. Upon the rod, (S5, are two spaced apart collars. (5Fl. which alternati-ily, according to the direction ol`A swine' ol the builder arm, engage a collar, (if), through which the rod, (55, slides and is attached to the arm, Cel, by the eye, (il, and thus the to and 'tro movement oli the arm. tt, elierted. The number of teeth through which the ratchet wheel is turned depends upon the` adjustment oiT the collars on the rod, (i5. The rod, (35, may also, as shown in 'full lines in Fie'. l, he used to vibrate an arm, Ttl. which carries a pawl, Tl, that eoacts with a ratchet wheel, 72, to rotate a bevel pinion. a tached to the ratchet wheel, which pinion meshes with a. bevel pinion, Tt, on a shaft 75, which is journaled in hearings, Tt, on the side of the builder motion arm. l. 0n the shalt., 75, is a worm '77, which meshes with a worm wheel, 7S, mounted on a stud shai't, 75l, secured to the builder motion arm, and connected with the worin wheel,78,is a pinion, St), which meshes with a spur near, til, on a stud shalt, 82, on the builder motion arm, which rear til, meshes with a similar lgear,l 83, on a stud shalt, 8l, on the builderniw spinning-element support, alternately acting power means, an operative connection between the latter and said lever, and means for changing the direction of action of said power means connected with and receiving motion from said lever.
